+# pvtsutils
+pvtsutils is a set of common utility functions used in various Peculiar Ventures TypeScript based projects.
+
+## Install
+
+```
+npm install pvtsutils
+```
+
+## Using
+
+```javascript
+const utils = require("pvtsutils");
+```
+
+The `pvtsutils` namespace will always be available globally and also supports AMD loaders.
+
+## Types
+
+There is an [index.d.ts](./index.d.ts) file which makes easy to use current module as external
+
+## Helpers
+
+### Convert
+
+Helps to convert `string` to `ArrayBuffer` and back
+
+Convert support next encoding types `hex`, `utf8`, `binary`, `base64`, `base64url`. `utf8` is default.
+
+#### Examples
+
+Converts string to buffer
+
+```javascript
+const buf = Convert.FromString("some string", "hex");
+```
+
+Converts buffer to string
+
+```javascript
+const str = Convert.ToString(buf, "utf8");
+```
+
+### assign
+
+Copies properties from objects to a target object. [More info](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Object/assign)
+
+#### Example
+
+```javascript
+const obj = assign({}, {name: "Bob"}, {age: 12}); // {name: "Bob", age: 12}
+```
+
+### isEqual
+
+Returns `true` if 2 ArrayBuffers are equal
+
+### combine
+
+Combines some `ArrayBuffer` values
+
+#### Example
+
+```javascript
+const buf1 = new Uint8Array([1, 2, 3]);
+const buf2 = new Uint8Array([4, 5, 6]);
+const buf = combine(buf1, buf2); // [1, 2, 3, 4, 5, 6]
+```
+
+Some example capabilities included in pvtsutils include:
+
+- Converting values to adn from hex,
+- Converting values to and from base64,
+- Working with base64 url,
+- Working with binary data.
+- And more...
